Socket events not processed when user moves or resizes window
Posted: Fri May 11, 2018 7:25 pm
I have this problem working with socket events, I'm receiving data from TCP client handling reception with events.
It works fine, I process data from client and then show a message in wxTextCtrl (multiline) with information for user.
But when I move window or select text in wxTextCtrl my app doesn't send any kind of data to client.
I'm not working with secondary threads for this at the moment.
Function working with event EVT_SOCKET(SOCKET_ID_REG, ServerDialog::OnSocketEventReg):
I was searching in forum and something like this viewtopic.php?t=42379 sounds similar.
